An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-8901 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/awslabs/aws-alb-route-directive-adapter-for-istio (Go): affected all versions; no fix listed\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2024-8901/ (Markdown: https://insights.sbomify.com/CVE-2024-8901/index.md)","id":"CVE-2024-8901","markdown":"https://insights.sbomify.com/CVE-2024-8901/index.md","name":"CVE-2024-8901","record":{"aliases":["GO-2024-3210"],"analysis":{"component_type":"cloud_service","fix_type":"end_of_life","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"AWS ALB Istio Adapter","requires_auth":"none","summary":"Attackers can bypass OIDC authentication by spoofing JWTs if ALB targets are publicly exposed, affecting users of the deprecated AWS ALB Route Directive Adapter.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMZN","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"The  AWS ALB Route Directive Adapter For Istio repo https://github.com/awslabs/aws-alb-route-directive-adapter-for-istio/tree/master  provides an OIDC authentication mechanism that was integrated into the open source Kubeflow project. The adapter uses JWT for authentication, but lacks proper signer and issuer validation. In deployments of ALB that ignore security best practices, where ALB targets are directly exposed to internet traffic, an actor can provide a JWT signed by an untrusted entity in order to spoof OIDC-federated sessions and successfully bypass authentication.\n\nThe repository/package has been deprecated, is end of life, and is no longer supported. As a security best practice, ensure that your ELB targets (e.g. EC2 Instances, Fargate Tasks etc.) do not have public IP addresses. Ensure any forked or derivative code validate that the signer attribute in the JWT match the ARN of the Application Load Balancer that the service is configured to use.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Lack of JWT issuer and signer validation","id":"CVE-2024-8901","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"auth_bypass","year":"2024"},"n_packages":1,"n_references":2,"next":{"headline":"Information disclosure in Addon Elements for Elementor (formerly Elementor Addon Elements)","id":"CVE-2024-8902"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/awslabs/aws-alb-route-directive-adapter-for-istio","purl":"pkg:golang/github.com/awslabs/aws-alb-route-directive-adapter-for-istio","source":"GO-2024-3210"}],"prev":{"headline":"Security feature bypass in Firefox","id":"CVE-2024-8900"},"products":["AWS ALB Route Directive Adapter For Istio"],"published":"2024-10-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-14","vendors":["Amazon"]},"summary":"Attackers can bypass OIDC authentication by spoofing JWTs if ALB targets are publicly exposed, affecting users of the deprecated AWS ALB Route Directive Adapter.","url":"https://insights.sbomify.com/CVE-2024-8901/"}
